摘　　要：提出了一种比较不同编码速率的方法,并使用此方法分析了不同节点下基于V-BLAST和STBC两种虚拟MIMO方案的性能,得出了虚拟MIMO方案选择的一些结论。采用理论分析与Mento Carlo仿真相结合的方法,仿真结果为虚拟MIMO方案选择提供了理论依据,这对加速无线传感网的发展与应用无疑有重要意义。A new method for comparing different coding rate was proposed, With this method the performance of STBC and V-BLAST based virtual MIMOs comprising different nodes was compared and some conclusions were got about scheme selecting of virtual MIMO. Both the theoretical analyse and Mento Carlo simulation show that the results are very useful to select virtual MIMO schemes, which is very important to accelerate the development and application of WSN.
